Eucalyptus longissima is a mallee that typically grows to a height of 8 m (26 ft) and forms a lignotuber. It has smooth greyish brown bark, usually with rough, fibrous or stringy bark on most of the trunk. The adult leaves are lance-shaped, 55–110 mm (2.2–4.3 in) long, 7–16 mm (0.28–0.63 in) wide on a petiole 10–20 mm (0.39–0.79 in) long. The flower buds are arranged in groups of between seven and fifteen in leaf axils on an unbranched peduncle 7–17 mm (0.28–0.67 in) long, the individual buds on pedicels 3–7 mm (0.12–0.28 in) long. Mature buds are narrow oval to spindle-shaped, 7–12 mm (0.28–0.47 in) long, 2–6 mm (0.079–0.236 in) wide with a conical to horn-shaped operculum 4–9 mm (0.16–0.35 in) long. Flowering has been observed in most months and the flowers are white. The fruit is a woody, shortened spherical capsule 4–6 mm (0.16–0.24 in) long and wide.
